windows help requests

Is there any way in suse to respond to windows help requests. ie take control of a remote pc via the help request route??

You may use krdc to connect to Windo$ machines. I haven’t used it myself but is supports RDP protocol and that is what you want to connect to Windo$.
There are other technologies like NX too.

VNC and (x)RDP both work from openSUSE (client) to a windows machine (server).

See here: TightVNC (VNC Xvnc) on openSUSE as Client or Server (Remote Desktop Connections)
and here: Windows Linux RDP Remote Desktop Connections using openSUSE as Client or Server (terminal server)
